Question

Sendo A (2,5) B (1,0) e G (4,2) determine as coordenadas do ponto C Me ajudem por favor.

Answer 1

Explicação passo-a-passo:

• $\sf x_G=\dfrac{x_A+x_B+x_C}{3}$

$\sf 4=\dfrac{2+1+x_C}{3}$

$\sf 2+1+x_C=3\cdot4$

$\sf 3+x_C=12$

$\sf x_C=12-3$

$\sf x_C=9$

• $\sf y_G=\dfrac{y_A+y_B+y_C}{3}$

$\sf 2=\dfrac{5+0+y_C}{3}$

$\sf 5+0+y_C=3\cdot2$

$\sf 5+y_C=6$

$\sf y_C=6-5$

$\sf y_C=1$

Logo, $\sf C(9,1)$
